4 Claims.

This invention relates to an ink well mounting, and has as its primaryobject the provision of an efiective means for aifording a connectionbetween the annular base of an ink well and a slab which is so formed asto afford ready engagement and disengagement of the ink well and slab.

Another object is to provide a means for fastening an ink well base to aslab without effecting positive engagement with the latter, and whichwhile affording a secure connection between the ink well and the slabwill permit of ready detachment and replacement of the ink well.

While the invention is applicable for use in connection with slabs ofvarious materials, it is especially designed to be applied to slabs ofmarble, glass, stone, and similar hard and brittle materials which arediflicult to work to form. a

vention contemplating a means for aifordinga frictional grip between asmooth bore in the slab and smooth periphery of an ink well base.

With the foregoing objects in View, together with such other objects andadvantages as may subsequently appear, the invention resides in theparts and in the combination, construction and arrangement of partshereinafter described and claimed, and illustrated by way of example inthe accompanying drawing, in which:

Fig. l is a perspective view of a ring clamping element;

Fig. 2 is a detail in cross section taken on the line 2-2 of Fig. 1;

Fig. 3 is a perspective View showing an ink well mounted on a slab inaccordance with the invention;

Fig. 4 is a detail in section taken on the line 4-4 of Fig. 3.

Referring to the drawing more specifically, A indicates a slab formed ofany suitable solid material having a circular opening 6 formed thereinand which slab may be covered on its under side with a sheet padding 1formed of felt or similar material and which sheet may extend over theopening 6, as particularly shown in Fig. 4.

An ink well B formed with a cylindrical base 8 is designed to be mountedin the opening 6; the base 8 being formed with an outwardly extendingmarginal flange 9 on its lower edge having an external diameter slightlyless than the diameter of opening 6. Mounted on the upper portion of thecylindrical base 8 is an outwardly and downward 1y extending flange illthe outer margin of which positive connection therewith; the presentinis adapted to seat on the upper face of the slab A.

In carrying out the invention, a split ring C is provided. The ring C isformed of a strip of resilient sheet metal, so as to have a spring acll, (assuming the ring to be disposed horizontally) the connecting endportions of which tongues protrude inwardly and downwardly from theinner periphery of the ring and the lower free end portions of whichterminate in inwardly spaced relation to the inner periphery of the ringas particularly shown in Fig. 2.

In the application and operation of the invention, the spring C ispositioned in the opening 6 whereupon the cylindrical base of the inkwell B is inserted in the ring with the flange 9 thereof bearing againstthe tongues H; the outer periphery of the flange 9 being of a diameterexceeding that of a circular line defining the faces of the inwardlyprojecting connected end portions of the tongues ll so as to snap by theconnected end portions of the tongues and thereafter press the free endsof the tongues toward the inner periphery of the ring, therebycollectively placing the tongues under tension and causing the I tonguesto grip the flange 9 and at the same time exert outward radial thrustson the ring C such as to augment the pressure of the ring against thewall of the opening 6. The upper connecting end portions of the tonguesII will then overlie the marginal flange 9 on the ink well and will thenact to yieldably oppose separation of the ink well base and the splitring. In thus positioning the ink well in the opening fi the flange Illthereon is disposed to bear upon the top face of the slab A adjacent themargin of the opening so as to extend over the upper edge of the ring 5and the gap between the inner periphery thereof and the outer perimeterof the base 8 thus concealing the spring ring and affording a neatfinish.

It will now be seen that the spring ring will afford a grip between theink well and the slab which while holding the ink well againstaccidental displacement will permit of ready rethe ring will bewithdrawn from the slab with the ink well.

1. In an ink well mounting, a slab formed with a circular opening, anink well having a cylindrical base formed with an outwardly extendingflange on its lower margin, said base being disposed in said opening, aresilient ring interposed between the wall of said opening and the outerperiphery of said flange, and a series of spring tongues on said ringprojecting inwardly there from engaged by the outer periphery of saidflange and placed under tension thereby; said tongues having theirconnected end portions pro- Jecting over the upper edge of said flange.v

2. In an ink well mounting, a slab formed with a circular opening, anink well having a cylindrical base formed with an outwardly extendingflange on its lower margin, said base being disposed in said opening, aresilient ring interposed between the wall of said opening and the outerperiphery of said flange, and a series of spring tongues struck fromsaid ring and projecting inwardly and downwardly therefrom said flangebearing against said tongues intermediate their ends with the tonguesplaced under tension thereby, and a flange on said ink well seating onthe upper face of said slab.

3. In an ink well mounting, a slab formed with an opening, a split ringslidably seated on the wall of said opening in frictional engagementtherewith, a series of spring tongues struck from said ring andprojecting inwardly and downwardly therefrom with their connectingportions leading from adjacent the upper margin of said ring, and an inkWell base inserted in the space bounded by said ring, a marginal flangeon said base slidably engaging said spring tongues intermediate theirends; said tongues being placed collectively under tension by pressureof said base flange thereon and acting to press said ring intofrictional engagement with the wall of said openmg.

4. In an ink well mounting, a slab formed with an op ening, a split ringseated on the wall of said opening, a series of spring tongues struckfrom said ring projecting inwardly therefrom with their connectingportions leading from adjacent the upper margin of said ring, an inkwell base inserted in the space bounded by said ring, a marginal flangeon said base having its periphery engaging said spring tonguesintermediate their ends; said tongues being placed collectively undertension by pressure of said base flange thereon and acting to press saidring into engagement with the wall of said opening; the connecting
